I V MARKING ATTACHMENT-FOR CORN-PLANTERS.

To all whom it may concern:

Be it known that I, Omvnu SMITH, a citizen of the United States,residing at Sully, in the county of Jasper, Stateof Iowa, have inventedcertain new and useful Improvements in Marking Attachments for Corn-Planters; and I do hereby declare the follow .ing to be a full, clear.and exact description of the invention, such as will enable othersskilled in the art to which it appertains to makeand use the same.

The present invention relates to improvements in marking attachments forcorn planters, and it has for its primary object the provision of anextremely simple and effective device of that nature which maybe readilyattached to the frame of a corn-planter of any ordinary type, may beswung to either side of the machine by means of a foot lever, thusleaving the hands of the driver free, and which will be positivelyguided and held against displacement during its swingmg movements.

More especially, the invention resides in the specific construction ofthe staff of the marker, in the particular manner inwhich the marker ismounted with reference to the frame of the machine, and to the guidescarried thereby, in the particular mechanism employed for effecting theswinging movement of the marker, and in the particular manner in whichthe latter is connected with such mechanism.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, in which corresponding parts or features, asthe'case may be, are designated by the same reference numeralsthroughout the several views, wherein:

Figure 1 is a plan View of the complete invention, showing the markerlowered. Figs. 2 and 3 are respectively, transverse and longitudinalsections taken on the lines 22 and 3-3 of Fig. 1. Figs. 4 and 5 aredetail views, respectively, of the marker and of the crank lever bywhich it is operated. Fig. 6 is a side elevation of the invertion,showing the marker in upright position. Fig. 7 is an enlarged detailview of the bracket in which the lever and drive shaft are journaled.

Referring more particularly to the draw ings, 5 designates the frame ofthe corn planter, which latter may be of any ordinary type now in use,the longitudinal sills of said frame being provided intermediate theirends with bracket hearings in which the axle Specification of'IiettersPatent.

sills are connected together by a cross-beam S, and at their rear endsby a pair of parallel cross-beams 9 and 10 arranged in spaced relationto each other, the portions of each sill between the last mentionedbeams and directly in front of the beam 9 being bent downwardly to formthe seats 11 shown in Figs. 3 and 6.

Upon each of the beams 9 and 10 is mounted an upstanding metal arch l2,which, in consequence of the above-described arrangement of said beams,are likewise disposed in spaced relation to and parallel with .each

The rear beam 10 has set into its inner side face, intermediate the endsthereof, a horizontal pin 13 to which the marker rod 14 is pivoted atits inner end, said rod carrying at its outer end a revoluble markingdisk 15. The marker, as a whole, is thus capable of a swinging movementin a vertical plane between the arches 12, which thus not. only serve toguide the marker during such movements, but also to hold it againstlateral displacement, the movement of the marker in either directionbeing limited by its contact with the corresponding seat 11, the heightof the beam 10 and the depth of the seats being sufficient to permit themarking disk to contact with the ground when the marker rod finger 19which, however, extends in the.0p-"

posite direction from the finger l7 and pro-.- jects through the lowerof a pair of horizontal openings 20 and 21 formed in an upstandingbracket 22, mounted upon the beam 9, the fingers 17 and .19 beingheldagainst displacement from the slot 16 and opening 21, respectively,by any preferred devices.

The finger 19 has rigidly secured thereto a gear 23, which meshes with alarger gear 24 carried by a shaft 25 which is disposed longitudinally ofthe frame of the machine and has its rear end projecting through theupper opening 20 in the bracket 22, while its front end is journaled ina bracket hearing secured to a cross beam 26 whose ends are fastened tothe side sills of the frame, the extreme rear end of said shaft havingsecured. thereto a treadle 27. The treadle is arranged for opera- I tionby the feet of the occupant of the seat -When, therefore, either end ofthe treadle is depressed, the consequentrotation of the shaft 25 will betransmitted to the crank lever 18- through the gears 24 and 23,whereupon said lever, and with it the marker, will be swung in avertical plane, the direction of movement of the lever and marker beingopposite to the direction of rotation of the shaft 25. Thus, when'theright hand end of the treadle, with respect to Fig. 1, is depressed, themarker will be swung downwardly to the left and vice versa. It will thusbeunderstood that the movements of the marker are controlled entirely bythe treadle which is operated "by foot pressure,

the hands of the operator being thus left free.

During the progress of the machine and while the marker is not in use,it may be retained in vertical position by pressure upon both ends. ofthe treadle.

\Vhat is claimed is:

1. In a machine of the class described, the combination, with a pivotedmarker, of a lever disposed parallel with the marker and provided ateach end with a crank finger; one of said fingers being engaged withsaid marker; a gear secured to the other finger; a shaft disposed at ri'ht angles to said lever; a gear-secured to said shaft in mesh with thefirst-mentionedgear; and means for rotating said shaft in eitherdirection, to swing said lever and said marker in a vertical plane.

2. In a machine of the class described, the combination, with a pivotedmarker pro vided intermediate its ends with a slot; of a lever pivotedat one end and provided at its other end with a crank finger engaged inthe ,lot in the marker; a gear secured to the pivoted end of the lever;a shaft-disposed at right an les to said lever; a ear secured to saidshaft in mesh with the first mentioned gear; and means for rotating saidshaft in either direction, to swing said lever and said marker in avertical lane.

3. In a machine of the class described, the

combination, with a pivoted marker provided intermediate its ends with aslot; of a lever pivoted at one end and provided at its other end with acrank finger engaged in the slot in the marker; a gear secured to thepivoted end of the lever; a shaft disposed at right angles to saidlever; a gear secured to one end of the shaft in mesh with thefirstmentioned gear: and a treadle secured to the other end of saidshaft, for rotatin the same in either direction, to swing said over andsaid marker 111 a vertical plane.

4. In a maclnne of the class described, the

combination, with a frame including parallel side sills, of a pair ofspaced upstanding arches arranged transversely of the frame and havingtheir ends secured to said sills; a'marker pivoted at its inner end tothe frame for movement in the space between said arches; a lever disosed )arallel with the marker and providerl at eac 1 end with a crankfinger; one of said fingers being engaged with said marker; a gearsecured to the other fin er; a shaft disposed at right angles to saidlover; a gear secured to said shaft in mesh with the first-mentionedgear; and means for rotatin said shaft in either direction, to swingsaid lever and said marker in a vertical plane.

5. In a machine of the class described, the combination, with a frameincluding parallel side sills, of a pairof spaced upstanding archesarranged transversely of the frame and having their ends secured to saidsills; a marker pivoted at its inner end to the frame, for movement inthe space between said arches, said lever being provided intermediateits ends with a slot; a lever pivoted at one end and provided at itsother end with a crank finger enga ed in the slot in the marker; a gearsecured to the pivoted end of the lever; a shaft disposed at rightangles to said lover;

a gear secured to one end of the shaft in mesh with the first-mentionedgear; and a treadle secured to the other end of said shaft, for rotatinthe same in either direction, to swing said Iever and said marker in avertical lane.

In testimony whereof, I affix my signature, in presence of twowitnesses.
